DOCOMO and NEC test O-RAN compliant 5G SA

NTT DOCOMO and NEC completed interoperability testing for 5G standalone (SA) using a 5G base station baseband unit (5G CU/DU) conforming to O-RAN open interface specifications and radio units (RUs) of different vendors.

The multi-vendor interoperability test used a software upgrade to introduce SA capability to NEC's 5G non-standalone (NSA) CU/DU operating on DOCOMO's commercial network. As a result, the system was transformed from a 5G NSA system into a 5G SA system using the same 5G CU/DU hardware. Since the 5G CU/DU can also accommodate existing NSA, the unit can be used to flexibly and quickly upgrade a 5G network.

The SA system enables network operators to flexibly provide services that take advantage of 5G features, such as eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), and URLLC (Ultra-Reliable and Low Latency Communications), enabling support for the diverse demands of 5G, including the enhancement and sophistication of solutions for corporate customers.

Moving ahead, DOCOMO and NEC will continue to verify the performance of 5G CU/DU, and aim to introduce new units to DOCOMO's commercial network, resulting in expanded 5G coverage with sophisticated base station equipment that enables superior 5G service.

NEC to build 24-fiber-pair transatlantic cable for Facebook

NEC has been contracted by Facebook to build an ultra-high performance transatlantic subsea fiber-optic cable connecting the USA and Europe. The project will use NEC’s newly developed 24 fiber pair cable and repeater, enabling the system to deliver a maximum transmission capacity of a half Petabit per second, the highest to date for a long-distance repeatered optical subsea cable system.


Facebook confirmed its first-ever transatlantic, 24-fiber-pair subsea cable system will connect Europe to the United States, buiding on its recent news about 2Africa Pearls, the subsea cable connecting Africa, Asia, and Europe.

Facebook also announced a second generation of its Bombyx robot, which climbs and then install fiber over medium-voltage power lines. The updated design is lighter, faster, and more agile. 

In addition, Facebook's Terragraph radios are now being used to deliver high-speed internet to more than 6,500 homes in Anchorage, Alaska, and deployment has started in Perth, Australia. Facebook licenses Terragraph for free to OEMs who have collectively shipped more than 30,000 Terragraph units to more than 100 service providers and system integrators around the world. 


NEC targets subsea cables to 24 fiber pairs and beyond

NEC and its subsidiary OCC Corporation completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers). This represents a 25% improvement in fiber count over 16 fiber pair systems previously built by NEC.

NEC said it achieved this milestone with only minor modifications to its proven repeater and cable designs. This was done by optimizing key repeater components, and by proving that its existing cable design could easily accommodate more fibers. The 20 fiber pair repeaters continue to use quadruple pump sharing technology, first introduced by NEC in 2010, for high optical and electrical efficiency.


OCC’s 20 fiber pair cable can be manufactured using a wide range of existing optical fibers, according to the needs of each new cable system. Furthermore, OCC has demonstrated to its customers that they can visually identify individual fibers using a combination of ring marking and conventional fiber coloring. This allows the potential number of fibers in a cable to be greatly expanded. Significantly, in OCC cable, the fiber’s transmission performance is completely unaffected, either by the fiber coloring or cabling processes.

“As global capacity demand continues to soar, NEC is committed to helping our customers scale up their networks in a cost-effective way,” said Takaaki Ogata, Executive Technical Manager of NEC’s Submarine Network Division. “Further significant increases in the fiber pair count of NEC’s wet plant are coming soon,” he added.

Mass production of the newly-qualified subsea repeaters and optical cable has already started.

2Africa will be longest subsea cable system in the world

The 2Africa cable system will add an extension to the Arabian Gulf, India, and Pakistan, bringing its total length to over 45,000 kilometers, making it the longest subsea cable system ever deployed.  

The 2Africa consortium includes China Mobile International, Facebook, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone and WIOCC.

Now connecting three continents, Africa, Europe and Asia terrestrially through Egypt, 2Africa creates unique connectivity by adding vital landing locations in Oman (Barka), UAE (Abu Dhabi and Kalba), Qatar (Doha), Bahrain (Manama), Kuwait (Kuwait), Iraq (Al-Faw), Pakistan (Karachi), India (Mumbai), and a fourth landing in Saudi Arabia (Al Khobar). The new 2Africa branch joins recently announced extensions to the Canary Islands, the Seychelles, Comoros Islands, Angola, and a new landing to south-east Nigeria.

As with other 2Africa cable landings, capacity will be available in PEARLS landings at carrier-neutral facilities or open-access cable landing stations on a fair and equitable basis, encouraging and supporting the development of a healthy internet ecosystem. 

Alcatel Submarine Networks (ASN) will deploy the new system utilizing new technologies such as SDM that allow the deployment of up to 16 fiber pairs.



2Africa subsea cable boasts design capacity up to 180 Tbps

2Africa, a new subsea cable to serve the African continent and Middle East region, promises to deliver more than the total combined capacity of all subsea cables serving Africa today, with a design capacity of up to 180Tbps on key parts of the system.

Consortium partners include China Mobile International, Facebook, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone and WIOCC.

Alcatel Submarine Networks (ASN) has been selected to build the fully-funded cable. The project will leverage SDM1 (space division multiplexing) technology from ASN, allowing deployment of up to 16 fiber pairs instead of the eight fiber pairs supported by older technologies. The cable will incorporate optical switching technology to enable flexible management of bandwidth. Cable burial depth has also been increased by 50% compared to older systems, and cable routing will avoid locations of known subsea disturbance, all helping to ensure the highest levels of availability.

The 2Africa subsea cable will span 37,000km long, interconnect Europe (eastward via Egypt), the Middle East (via Saudi Arabia), and 21 landings in 16 countries in Africa. The system is expected to go live in 2023/4. Each of the cable landing sites will offer carrier-neutral data centers or open-access cable landing stations on a fair and equitable basis.

In addition, the 2Africa parties and Airtel have signed an agreement with Telecom Egypt to provide a completely new crossing linking the Red Sea and the Mediterranean, the first in over a decade. This includes new cable landing stations and deployment of next-generation fiber on two new, diverse terrestrial routes parallel to the Suez Canal from Ras Ghareb to Port Said, and a new subsea link that will provide a third path between Ras Ghareb and Suez.

NEC qualifies subsea repeaters and cables for 24 fiber pairs

 NEC and its subsidiary OCC Corporation have completed full qualification of subsea repeaters and optical cable containing up to 24 fiber pairs (FPs) (48 fibers). The new qualification is a 50% improvement in fiber count over the 16 fiber pair systems generally available today. 

Only minor modifications were needed to NEC's existing repeater and cable designs. Keeping NEC's quadruple pump redundancy in the repeater (established more than 10 years ago) and maintaining OCC's outstanding cabling performance has resulted in cabled attenuations lower than 0.150dB/km. Low attenuation is critical to achieve large spectral efficiency as well as lower power consumption.

NEC said the qualification will allow for the construction of subsea telecom cables with superior traffic capacity while reducing the cost per bit of the wet plant. The development is fully in line with SDM (Space Division Multiplexing) system architectures. 

"As global demands for capacity and FP flexibility continue to soar, NEC is committed to helping our customers to build up their subsea networks with large spectral efficiency, lower power consumption and large-scale subsea connectivity," said Yoshihisa Inada, Deputy General Manager and Head of Subsea Technology Development at NEC's Submarine Network Division.  "We continue to evaluate multiple technical options to further increase capacity and reduce the cost/bit of the networks."

OCC's 24 fiber pair cable can be manufactured using a wide range of existing optical fibers, according to the needs of each new cable system. Each fiber can be visually identified using a field-proven combination of ring marking and conventional fiber coloring, first introduced in 2013. Furthermore, in OCC cable, the fiber's transmission performance is completely unaffected, either by the fiber marking or cabling processes.

"We have concluded that the use of our fibers in OCC's 24 pair cable results in a cabled attenuation matching the nominal value. We are confident that our ultra-low-loss fibers can contribute to achieve large capacity, high spectral efficiency and low power consumption in transoceanic networks," said Dr. Masashi Onishi, General Manager at Optical Fiber and Cable division of Sumitomo Electric Industries Ltd.

"To support growing bandwidth, next generation subsea systems will offer Petabit-scale transmission. To achieve the required performance, cabling processes must capture the advantaged optical attenuation and large effective area of our ultra-low-loss fibers. OCC's cabling process for 24 fiber pairs works with our high quality fiber to meet the challenge," said Dr. Bernhard Deutsch, VP & GM, Optical Fiber & Cable, Corning Incorporated.

NEC targets subsea cables to 24 fiber pairs and beyond

NEC and its subsidiary OCC Corporation completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers). This represents a 25% improvement in fiber count over 16 fiber pair systems previously built by NEC. NEC said it achieved this milestone with only minor modifications to its proven repeater and cable designs. This was done by optimizing key repeater components, and by proving that its existing cable...

NEC delivers submarine cable seismic and tsunami observation system

NEC has delivered a submarine cable seismic and tsunami observation system to Taiwan's Central Weather Bureau (CWB) under the Ministry of Transportation and Communications. The new system is mainly intended for observation of earthquakes and tsunami in the area ranging from the offshore coast of Yilan in eastern Taiwan to Fangshan in Pingtung County. 

The submarine cable measures 620 kilometers and reaches a depth of 5,800 meters. All products, including optical submarine cables, submarine observation units, and optical submarine repeaters, which constitute the system, were manufactured and assembled at NEC factories in Japan.

According to the CWB, when an earthquake occurs in the eastern sea area of Taiwan this new system can provide an emergency warning more than 10 seconds before the actual tremor is felt on land. Moreover, a warning can be issued 20 to 30 minutes before a tsunami reaches the coastal area. As a result, this system will contribute to the enhancement of disaster prevention and mitigation capabilities. For example, public transportation systems, including MRTs (Mass Rapid Transit) and HSRs (High Speed Rail) can quickly decelerate in the event of an earthquake.

Atsushi Kuwahara, General Manager, Submarine Network Division, NEC Corporation, said, "It is a great honor that the NEC Group can use its many years of experience in optical submarine cable communication technology and submarine observation technology to help prevent disasters and ensure safety for the residents and government of Taiwan. Going forward, we will continue to provide technology and solutions that contribute to the well-being of our communities."

NEC triples number of connections in distributed-MIMO

NEC demonstrated multiple highly stable simultaneous terminal connections and transmission capacity through distributed-MIMO in the 28 GHz millimeter-wave frequency band. 

The company says its demonstration, which was conducted in a real world office environment, achieved approximately 3 times the number of simultaneous connections and transmission

capacity compared to cases without distributed-MIMO in the 28 GHzfrequency band. Moreover, transmission deterioration from obstacles was also reduced.

Earlier this year, Japan began to commercially deploy 5G in the sub 6 frequency band and millimeter-wave frequency band, with the expectation of enhancing network performance to support 10 times more capacity than 4G, as well as higher throughput, lower latency, and multiple connections.

NEC has been a pioneer in digital beamforming technology and has commercialized Massive-MIMO in the sub 6 frequency band. Moreover, NEC has developed digital coordination technology among antenna elements distributed in the millimeter-wave frequency band and conducted verification activities to solve the problems of indoor mobile communications, such as shadowing and diffraction of propagation paths.

NEC to build subsea cable in Palau

The National Submarine Cable Utility Belau Submarine Cable Corporation (BSCC) of the Palau Republic (Palau) has awarded a contract to NEC for the construction of the Palau Cable 2 (PC2) optical submarine cable.

The PC2 cable will have a total length of approximately 110km and connect Palau with another high-capacity cable linking southeast Asia to mainland U.S.  The new cable serves as an addition to the first optical submarine cable laid by NEC in Palau in 2017.

This project is being implemented under a buyer's credit loan agreement by the Japan Bank for International Cooperation (JBIC) and Sumitomo Mitsui Banking Corporation (SMBC)

with BSCC. The loan portion from SMBC is insured by Nippon Export and Investment Insurance (NEXI). Additional financing is being provided by the United States Government and the Australian Infrastructure Financing Facility for the Pacific (AIFFP).


NEC begins construction of 3 subsea cables in Micronesia

NEC, in partnership with Belau Submarine Cable (BSCC) and the government of the Federated States of Micronesia (FSM), announced it has commenced construction of three submarine cable links that will connect the islands of Palau, Yap and Chuuk in the western Pacific Ocean to the global network.

BSCC, supported by a loan from the Asian Development Bank (ADB), has signed a supply contract with NEC to build the spur to Palau, while FSM, backed by a grant from the World Bank (WB), has signed a supply contract with NEC to construct the spur to Yap, and recently signed an additional agreement for the extension from Pohnpei to Chuuk.

The spurs to Palau and Yap will both interconnect with the SEA-US cable system, also under construction by NEC, which connects the Philippines and Indonesia to the west coast of the U.S. via Guam and Hawaii. In addition, the extension from Pohnpei, the capital of FSM, to Chuuk branches out of another existing cable linking FSM, the Marshall Islands and Guam. All three routes feature transmission speeds of 100 Gbit/s per channel.

BSCC is a state-owned entity of the Republic of Palau with responsibility for the submarine cable project. BSCC has signed an IRU agreement with GTI (a subsidiary of Globe Telecom) for the provision of 5 x 100 Gbit/s wavelengths and a branching unit (BU) on the SEA-US West subsystem linking Indonesia, the Philippines and Guam. It has also contracted NEC to supply a spur cable linking the BU on the SEA-US West subsystem to Palau.

On completion of the project, BSCC will provide open bandwidth access to the international cable system for domestic telcos.

In addition, DTCI has signed an IRU agreement with Telkom Indonesia (Telin) for 5 x 100 Gbit/s wavelengths and a BU on the main trunk of the SEA-US West subsystem, plus a supply contract with NEC to deliver a spur cable linking the BU on the SEA-US West subsystem to Yap, along with a contract extension that includes a cable linking Weno Island Chuuk to the existing spur on to the HANTRU-1 cable system in Pohnpei to Guam.

Ownership and implementation responsibilities for the cable systems will pass from DTCI to the newly established FSM Telecommunications Cable (FSMTCC) which, as owner of the Yap and Chuuk cable systems, will provide open bandwidth access to the international cable systems for domestic telcos.
